NAME

     kextstat -- display status of loaded kernel extensions (kexts)

SYNOPSIS

     kextstat [-a] [-h] [-k] [-l] [-b identifier] ...

DESCRIPTION

     The kextstat utility displays the status of any kexts currently loaded in the kernel.  The following information is shown for each loaded
     kext:

     Index     The load index of the kext (used to track linkage references).  Gaps in the list indicate kexts that have been unloaded.

     Refs      The number of references to this kext by others.  If nonzero, the kext cannot be unloaded.

     Address   The address in kernel space where the kext has been loaded.

     Size      The number of bytes of kernel memory that the kext occupies.  If this is zero, the kext is a built-in part of the kernel that has a
	       record as a kext for resolving dependencies among kexts.

     Wired     The number of wired bytes of kernel memory that the kext occupies.

     Architecture (if the -a option is used)
	       The architecture of the kext.

     Name      The CFBundleIdentifier of the kext.

     (Version)
	       The CFBundleVersion of the kext.

     <Linked Against>
	       The index numbers of all other kexts that this kext has a reference to.

OPTIONS

     These options are available:

     -a, -arch
	       Print the architecture of the kext.

     -b identifier, -bundle-id identifier
	       Display the status of only the kext with the given bundle identifier.  This option trumps the -no-kernel option; if both are given
	       and a kernel component is specified, its information is shown.

     -h, -help
	       Print a help message describing each option flag and exit with a success result, regardless of any other options on the command
	       line.

     -k, -no-kernel
	       Don't show information for built-in components of the kernel.

     -l, -list-only
	       Print the list of loaded kexts only and omit the header (useful for running output through text-analysis tools).

     -s, -sort
	       Sort the list by load address.

DIAGNOSTICS

     The kextstat utility exits with a status of 0 on success and with a nonzero status if an error occurs.
